# Setting up OAuth Keys for Outlook Calendar
To set up OAuth keys for Outlook Calendar, sign in to your Kloudless Account and go to the Third Party Services Configuration section. Navigate to the section for Outlook Calendar and click on the link. The instructions detail how to set up the Outlook Calendar application, and the permissions needed to extend access to the Kloudless integration.
# Creating/Registering an Outlook Calendar Application
# Required Scopes
Add the following Microsoft Graph "Delegated Permissions" on the "API permissions" page:
Calendars.ReadWrite.Shared Calendars.ReadWrite Contacts.Read Contacts.Read.Shared MailboxSettings.Read User.Read User.ReadBasic.All email offline_access openid profile
These permissions grant access to all resources Kloudless can reach. You can customize this list to only the resources your application requires. Doing so will reduce the permissions requested from the end-user.
For admin users of all Office 365 services, such as SharePoint, OneDrive for Business, and Outlook Calendar, custom scopes can only be configured via the Application Permissions screen in the Azure App Registry rather than dynamically as part of the Kloudless OAuth flow.
